Abstract: In a driving method of an ink-jet recording head, heat is generated by applying a drive signal to a heating element, and this heat is given to ink to generate a bubble and discharge ink through a discharge outlet. The drive signal comprises a first drive signal (t0-t1) for storing foaming energy in ink, and a second drive signal (t1-t2) for generating a bubble in ink. The second drive signal has a signal time shorter than the boundary foaming time (ts) at which foaming energy decreases in case of performing foaming only by the second drive signal. The first drive signal is applied prior to said second drive signal in order to compensate a decrease in foaming energy. The ink is heated over the boiling temperature Tb.
